The formula is
Explanation:
You are supposed to convert mass to moles using atomic and molecular weights.
Start with one mole of the carbohydrate. That is given as
Since to the nearest tenth,
And we then convert the carbon to moles by dividing by the atomic weight. Most periodic tables give this as
So one mole of the carbohydrate has six moles of carbon. That means the molecular formula has
For oxygen we do the same thing, but with the oxygen numbers:
So the formula will contain six oxygen atoms. Now we have
I will let you do the calculations for hydrogen. You should find the formula will contain
